----------------------------------
Summary: draining_servers.rb is broken
Key: HBASE-21629
URL: https://issues.apache.org/jira/browse/HBASE-21629
Project: HBase
Issue Type: Bug
Components: scripts
Affects Versions: 2.1.1, 3.0.0, 2.1.2
Reporter: Nihal Jain
Assignee: Nihal Jain
1) Handle missing methods and implementation changes in core code.
* In
[ZKWatcher.java|https://github.com/apache/hbase/blob/12786f80c14c6f2c3c111a55bbf431fb2e81e828/hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/ZKWatcher.java#L79],
variable znodePaths has now been made private from public (See HBASE-19761).
Currently the script directly tries to reference znodePaths which will result
in exception.
* Also, joinZNode method is moved to ZNodePaths and removed from ZKUtil (See
HBASE-19200). The script relies on non-existant ZKUtil.joinZNode().
2) Close zk watcher while list draining servers: The list functionality does
not close the zkw instance.
